What is the full car film provided by 4S stores?

In fact, the cost price of such films given by 4S stores generally does not exceed 300 yuan, so you can guess the quality of these films by their price. Unlike genuine automotive films, inferior car films are made with vastly different production processes. Generally, inferior automotive films mainly use dyeing techniques. As a result, these pigments are adsorbed on the surface of the film. Not only is the color difference severe, but they are also prone to deformation and bubbling under high temperatures. Additionally, they often come with unpleasant odors, containing large amounts of harmful substances such as formaldehyde and benzene, which pose significant health risks. High-quality automotive films are manufactured using magnetron sputtering technology. This process involves using a strong magnetic field to absorb precious and rare space metal atoms such as gold, silver, nickel, and titanium. Moreover, the coating features UV resistance and high-temperature resistance, providing excellent thermal insulation inside the car.
